This reverts commit cefdd52fa0455c0555c30927386ee466a108b060.
On sc7180-trogdor class devices with 'fw_devlink=permissive' and KASAN
enabled, you'll see a Use-After-Free reported at bootup.
The root of the problem is that dwc3_qcom_of_register_core() is adding
a devm-allocated "tx-fifo-resize" property to its device tree node
using of_add_property().
The issue is that of_add_property() makes a _permanent_ addition to
the device tree that lasts until reboot. That means allocating memory
for the property using "devm" managed memory is a terrible idea since
that memory will be freed upon probe deferral or device unbinding.
Let's revert the patch since the system is still functional without
it. The fact that of_add_property() makes a permanent change is extra
fodder for those folks who were aruging that the device tree isn't
really the right way to pass information between parts of the
driver. It is an exercise left to the reader to submit a patch
re-adding the new feature in a way that makes everyone happier.

For whatever reason, some devices like QCA6390, WCN6855 using ath11k
are not in M3 state during PM resume, but still functional. The
mhi_pm_resume should then not fail in those cases, and let the higher
level device specific stack continue resuming process.
Add an API mhi_pm_resume_force(), to force resuming irrespective of the
current MHI state. This fixes a regression with non functional ath11k WiFi
after suspend/resume cycle on some machines.

Martyn Welch reports that his CPU port is unable to link where it has
been necessary to use one of the switch ports with an internal PHY for
the CPU port. The reason behind this is the port control register is
left forcing the link down, preventing traffic flow.
This occurs because during initialisation, phylink expects the link to
be down, and DSA forces the link down by synthesising a call to the
DSA drivers phylink_mac_link_down() method, but we don't touch the
forced-link state when we later reconfigure the port.
Resolve this by also unforcing the link state when we are operating in
PHY mode and the PPU is set to poll the PHY to retrieve link status
information.

The driver currently assumes that the notify callback is only received
when the device is done with all the queued buffers.
However, this is not true, since the notify callback could be called
without any of the queued buffers being completed (for example, with
virtio-pci and shared interrupts) or with only some of the buffers being
completed (since the driver makes them available to the device in
multiple separate virtqueue_add_sgs() calls).
This can lead to incorrect data on the I2C bus or memory corruption in
the guest if the device operates on buffers which are have been freed by
the driver. (The WARN_ON in the driver is also triggered.)

[Why]
The HW interrupt gets disabled after S3/S4/reset so we don't receive

The registration of XDP queue information is incorrect because the
RX queue id we use is invalid. When port->id == 0 it appears to works
as expected yet it's no longer the case when port->id != 0.
The problem arised while using a recent kernel version on the
MACCHIATOBin. This board has several ports:
* eth0 and eth1 are 10Gbps interfaces ; both ports has port->id == 0;
* eth2 is a 1Gbps interface with port->id != 0.
Code from xdp-tutorial (more specifically advanced03-AF_XDP) was used
to test packet capture and injection on all these interfaces. The XDP
kernel was simplified to:
SEC("xdp_sock")
int xdp_sock_prog(struct xdp_md *ctx)
{
int index = ctx->rx_queue_index;
/* A set entry here means that the correspnding queue_id
* has an active AF_XDP socket bound to it. */
if (bpf_map_lookup_elem(&xsks_map, &index))
return bpf_redirect_map(&xsks_map, index, 0);
return XDP_PASS;
}
Starting the program using:
./af_xdp_user -d DEV
Gives the following result:
* eth0 : ok
* eth1 : ok
* eth2 : no capture, no injection
Investigating the issue shows that XDP rx queues for eth2 are wrong:
XDP expects their id to be in the range [0..3] but we found them to be
in the range [32..35].
Trying to force rx queue ids using:
./af_xdp_user -d eth2 -Q 32
fails as expected (we shall not have more than 4 queues).
When we register the XDP rx queue information (using
xdp_rxq_info_reg() in function mvpp2_rxq_init()) we tell it to use
rxq->id as the queue id. This value is computed as:
rxq->id = port->id * max_rxq_count + queue_id
where max_rxq_count depends on the device version. In the MACCHIATOBin
case, this value is 32, meaning that rx queues on eth2 are numbered
from 32 to 35 - there are four of them.
Clearly, this is not the per-port queue id that XDP is expecting:
it wants a value in the range [0..3]. It shall directly use queue_id
which is stored in rxq->logic_rxq -- so let's use that value instead.
rxq->id is left untouched ; its value is indeed valid but it should
not be used in this context.
This is consistent with the remaining part of the code in

'Commit 39f9895a00f4 ("vmxnet3: add support for 32 Tx/Rx queues")'
added support for 32Tx/Rx queues. Within that patch, value of
VMXNET3_LINUX_MIN_MSIX_VECT was updated.
However, there is a case (numvcpus = 2) which actually requires 3
intrs which matches VMXNET3_LINUX_MIN_MSIX_VECT which then is
treated as failure by stack to allocate more vectors. This patch
fixes this issue.

This commit fixes a misunderstanding in commit 4a3e0aeddf09 ("net: dsa:
mv88e6xxx: don't use PHY_DETECT on internal PHY's").
For Marvell DSA switches with the PHY_DETECT bit (for non-6250 family
devices), controls whether the PPU polls the PHY to retrieve the link,
speed, duplex and pause status to update the port configuration. This
applies for both internal and external PHYs.
For some switches such as 88E6352 and 88E6390X, PHY_DETECT has an
additional function of enabling auto-media mode between the internal
PHY and SERDES blocks depending on which first gains link.
The original intention of commit 5d5b231da7ac (net: dsa: mv88e6xxx: use
PHY_DETECT in mac_link_up/mac_link_down) was to allow this bit to be
used to detect when this propagation is enabled, and allow software to
update the port configuration. This has found to be necessary for some
switches which do not automatically propagate status from the SERDES to
the port, which includes the 88E6390. However, commit 4a3e0aeddf09
("net: dsa: mv88e6xxx: don't use PHY_DETECT on internal PHY's") breaks
this assumption.
Maarten Zanders has confirmed that the issue he was addressing was for
an 88E6250 switch, which does not have a PHY_DETECT bit in bit 12, but
instead a link status bit. Therefore, mv88e6xxx_port_ppu_updates() does
not report correctly.
This patch resolves the above issues by reverting Maarten's change and
instead making mv88e6xxx_port_ppu_updates() indicate whether the port
is internal for the 88E6250 family of switches.
Yes, you're right, I'm targeting the 6250 family. And yes, your
suggestion would solve my case and is a better implementation for
the other devices (as far as I can see).

dma_fence_chain_find_seqno only ever returns the top fence in the
chain or an unsignalled fence. Hence if we request a seqno that
is already signalled it returns a NULL fence. Some callers are
not prepared to handle this, like the syncobj transfer functions
for example.
This behavior is "new" with timeline syncobj and it looks like
not all callers were updated. To fix this behavior make sure
that a successful drm_sync_find_fence always returns a non-NULL
fence.
v2: Move the fix to drm_syncobj_find_fence from the transfer
functions.

Background:
We have a customer is running a Profinet stack on the 8MM which receives and
responds PNIO packets every 4ms and PNIO-CM packets every 40ms. However, from
time to time the received PNIO-CM package is "stock" and is only handled when
receiving a new PNIO-CM or DCERPC-Ping packet (tcpdump shows the PNIO-CM and
the DCERPC-Ping packet at the same time but the PNIO-CM HW timestamp is from
the expected 40 ms and not the 2s delay of the DCERPC-Ping).
After debugging, we noticed PNIO, PNIO-CM and DCERPC-Ping packets would
be handled by different RX queues.
The root cause should be driver ack all queues' interrupt when handle a
specific queue in fec_enet_rx_queue(). The blamed patch is introduced to
receive as much packets as possible once to avoid interrupt flooding.
But it's unreasonable to clear other queues'interrupt when handling one
queue, this patch tries to fix it.

After the below patch, the conntrack attached to skb is set to "notrack" in
the context of vrf device, for locally generated packets.
But this is true only when the default qdisc is set to the vrf device. When
changing the qdisc, notrack is not set anymore.
In fact, there is a shortcut in the vrf driver, when the default qdisc is
set, see commit dcdd43c41e60 ("net: vrf: performance improvements for

This patch ensures that the behavior is always the same, whatever the qdisc
is.
To demonstrate the difference, a new test is added in conntrack_vrf.sh.

In tunnels packet there can be two UDP headers:
- outer which for hw should be mark as ICE_UDP_OF
- inner which for hw should be mark as ICE_UDP_ILOS or as ICE_TCP_IL if
inner header is of TCP type
In none tunnels packet header can be:
- UDP, which for hw should be mark as ICE_UDP_ILOS
- TCP, which for hw should be mark as ICE_TCP_IL
Change incorrect ICE_UDP_OF for none tunnel packets to ICE_UDP_ILOS.
ICE_UDP_OF is incorrect for none tunnel packets and setting it leads to
error from hw while adding this kind of recipe.
In summary, for tunnel outer port type should always be set to
ICE_UDP_OF, for none tunnel outer and tunnel inner it should always be
set to ICE_UDP_ILOS.

If the hardware is constantly receiving unicast or broadcast packets
during driver load, the device previously counted many GLV_RDPC (VSI
dropped packets) events during init. This causes confusing dropped
packet statistics during driver load. The dropped packets counter
incrementing does stop once the driver finishes loading.
Avoid this problem by baselining our statistics at the end of driver
open instead of the end of probe.

The patch that implemented DSCP QoS implementation removed a
bandwidth check that was used to check for a specific condition
caused by some corner cases. This check should not of been
removed.
The same patch also added a check for when the DCBx state could
be changed in relation to DSCP, but the check was erroneously
added nested in a check for CEE mode, which made the check useless.
Fix these problems by re-adding the bandwidth check and relocating
the DSCP mode check earlier in the function that changes DCBx state
